AD DSP68 Audio System

The Audio System Italy AD DSP68 is a high-performance digital sound processor designed for the precise tuning of sophisticated car audio systems. With 6 input channels and 8 output channels, the DSP is suitable for both classic aftermarket systems and integration into vehicles with factory-installed audio systems.

32-bit digital signal processing at up to 192 kHz enables detailed processing of the audio signal. Using the accompanying DSP software, individual channels can be configured separately and adjusted directly in real time. In addition to time alignment and comprehensive signal routing, a matrix mixer is available that allows the input signals to be flexibly distributed across the eight output channels.

Thanks to its high-level and low-level inputs, the AD DSP68 can be combined with both aftermarket radios and OEM audio systems. A summing function allows you to combine frequency ranges that were already separated at the factory. An optical S/PDIF digital input is also available.

Up to 5 different setups or presets can be saved. Optionally, an external controller can be used to adjust the volume and switch between the saved setups. A Bluetooth expansion is also planned.
